The Juggernaut 1915

Back in college, John Ballard saved Philip Hardin's life. Twenty years later, John is the district attorney and Philip is president of a railroad notorious for its accident record. When John brings a suit against the railroad, Philip threatens to reveal a ruinous secret about John unless he drops the case. Meanwhile, a railroad inspector discovers that the trestle over which an express train carrying Philip's daughter is about to pass is in eminent danger of collapse.
